WWE star Dwayne Johnson says it's a proud moment for him to see his daughter Simone following in his footsteps and join WWE.

Johnson, who had a long career in professional wrestling before becoming a Hollywood star, said Simone, 18, will be the youngest signee in the history of WWE. "She signed her contract with the WWE, it just blows my mind," Johnson told Jimmy Fallon via video chat on 'The Tonight Show'.
